Effects of sin1 and caf mutations on flowering time and leaf no.
| Strain | Segregant Phenotype | n | Average Bolting Time | Average No. of Leaves | Significant Difference between Segregants |
|---|---|---|---|---|---|
| Columbia-glabrous1(Co-gl) | Wild type | 41 | 27.4 ± 1.4 | 9.1 ± 1.0 | – |
| sin1-1/+ (Co-gl) | Sin1+ | 32 | 28.1 ± 1.4 | 9.2 ± 0.9 | – |
| Sin1− | 10 | 45.0 ± 2.9 | 18.8 ± 2.7 | d > 99% | |
| sin1-2/+ (Co-gl) | Sin1+ | 33 | 28.4 ± 1.6 | 9.3 ± 1.0 | – |
| Sin1− | 15 | 41.0 ± 2.3 | 18.7 ± 2.0 | d > 99% | |
| sin1-1/+ (La-er) | Sin1+ | 38 | 27.9 ± 1.6 | 8.3 ± 0.8 | – |
| Sin1− | 15 | 42.5 ± 5.9 | 14.6 ± 2.8 | d > 99% | |

| Sin1− | 9 | 36.2 ± 3.6 | 12.3 ± 2.2 | d > 99% | |
| caf-1/+ (La-er) | Caf+ | 42 | 27.8 ± 2.0 | 8.4 ± 0.8 | – |
| Caf− | 7 | 35.0 ± 2.1 | 11.1 ± 1.7 | d > 99% |
Regardless of the genetic background, sin1 and caf mutants exhibit a delay in flowering (as assayed by the no. of days it took the plants to bolt), as well as an increase in the production of leaves. Data were analyzed using the Fisher-Behrens procedure (for means with unequal population variances), with the d value significant at the 99% level when comparing the mutants with their wild-type segregants, for both flowering time and leaf no. (Campbell, 1989). The data are presented as mean ± sd.
